I'd fold.

The way everyone is swinging at this pot there are plenty of bad cards that will beat you even if you do have the best hand.

However, that being said the way everyone played this hand you might have those other two guys beat. But that weird raise scares me. Why wouldn't he just shove it in? I'm way more afraid of that guy than the cold caller who most likely doesn't have a set. The pot is way too big to cold call with any type of big hand on that flop.

At least you know all of the players in that hand (other than you) are horrible players and you can most likely wait for a better spot.
